@ma .ma @met @una IMPROVEMENT IN TUYEBES.

T. E. C. BRINLY, `OF LO'ISVILLFL KETUCKY. lletters Patent No. 60,333, dated December 11, 1866.

TO ALL WHOM IT MAY CONOERN:

`Be it known that 4I, T. E. C. BRINLY, of Louisville, in the county of Jeerson, and -State of Kentucky, have invented a new and useful Improvement in Tuyere Irons; and I do herebyfdeclare that the following is a. full, clear, and exact description thereof.

The nature of my invention consists in the combination of hooks secured to the cap of a tuyere iron, with lugs or ears secured to the side of the body or chambe` of the tuyere, so that the cap eadily removed in order that access may be had to the interior of the air chamber of the tuvere for the rpose of removing the cinders that may have collected there.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation. v

i Figure 1 is a top plan view ofmy improved tuyere iron.

Figure s a longitudinal vertical sectional elevation from the line a: in

, Letters of'like name and kind refer to like parts in each of the figures A represents the` body of a tuyere made of cast iron or other suitable centre rising to the upper surface'of the body which forms the bed for tli-ef-lire, as shown at B,'in iig. 1. By meansv of the centre of the body being raised in the manner described, forms an annular air chamber, C, which connects with the pipe D. This pipe D connects with the pipe or tuyere ofthe bellows, through which the blast,

passes from the bellows into the annular chamber C. E is a cap made of .the same lmaterial as the body of the tuyere A, provided with a ilange, a, `that fits over the outside of the tuyere and secured thereto by means of hooks, e e e, which engage with the lugs or ears, n n n, upon the outside ofthe b ody of the tuyere, as shown in the model and drawings. In the centre of the cap Eis an aperture, circular in form, of proper dimensions, that is fitted to the top of the centre of the tuyere. The top of the centrclportion oi the body of the tuyere is made concave for the bed of th'e lire, and to prevent any obstruction to the blast as it isforced out between `the cap .and centre of the body of the tuyere. u shows the space between the centre'B and cap E, through which 4 I do not confine myself to the particular construction of the body of the tuyere provided with the cap, 'as it may be made in two sections and the sections secured in the samefmanner as shown# i The advantages of my invention will at once be observed, as the cap may at any time' be removed without disturbing the body of the tuyere or any liability of breaking or injuring any portion of the'tuyere, which is very liable to be the case when bolts are employed to'secure the cap in its position.

Having thus Adescribedmy invention, I claim as new and desire to secureby Letters Patent- The cap E, provided with a flange a, and hooks e e e, body A, with the raised centre fo'rming an annularair 4chamber C, and ears 'n` n n, when arranged as herein set forth andoperating as and for the purpose sp'ecihed.

The above specification of my invention, signed by me this 8th day of September, 1866.
